Factory 17's?

i just bought myself a taco with the sport package on the 11th it came with 17's.. do all sport packages come with 17's? i noticed alot of people saying they have 15's and 16's. and i have one other question.. if i buy an Air raid intake it voids my warranty am i correct? thanks guys.

The TRD Sports come with 17" rims, TRD Offroads come with 16" rims and base models come with 15" rims. Buying an air intake WILL NOT VOID the warranty unless the dealer can without a doubt prove that the intake caused a failure.
